I'm going to say a Human.
In one simple statement, Humans have survived all of earth's devastation because of evolution. At one point it is believed that the earth had changing conditions including that some of the food that we hunted in waters became extinct. Then, as lack of food grew, We gained the ability to walk on land. As this happened, we began to adapt to our surroundings, including gaining the ability to walk on two legs and use tools
f = 10000N
distance moved = 20 m
work done = 10000*20 = 200000
Answer:
<h3><em>
28.01m/s.</em></h3>
Explanation:
Given maximum height reached by the ball as H = 40 metres
Since the ball rises straight up when hit by a ball, then the angle of launch will be perpendicular to the ground and that is 90°.
To determine the upward speed of the ball in meters per second after it got struck by the bat, we will use the formula for calculating the maximum height according to projectile motion;
Maximum Height H =
where;
u is the speed of the ball
is the angle of launch
g is the acceleration due to gravity = 9.81m/s²
Substituting the given parameters into the formula;

<em>Hence the upward speed of the ball in meters per second after it got struck by the bat is 28.01m/s.</em>
Answer:
Tangential
Explanation: This is a kind of force which act on a moving body in such a way that it is curved in the direction of the path of the body. This implies that when the velocity of the object is positive, the acceleration will be negative.
